Black Holes

have black holes actually been proven to exist? when i was a kid i was all into astronomy and recently i've been looking into it again, and after reading several articles on the subject im still kinda in the dark. if you say wiki black holes there's tons of inferential information about them existing but no references to actual known black holes. also I just read some random post on /b/ (lol, reliable information) saying "as science has proven a blackhole is impossible (NASA news 2006) " <- anyone know wtf article he's referring to.

so tl;dr, blackholes: definately out there or an interesting theory?

You know what I do when I see verbal exchange or physical confrontation where seven people are bullying one person? I join and help that one person because I have principles and ideals. Most people would probably join the seven because it's easier, they don't care for what's right. I believe in fairness, not bullying. In the outcome of it I probably would lose respect from those seven people and my reputation might get damaged. So what? You know what it's about for most people? Save yourself (or in this case reputation). Why risk it to defend someone who the multitude seems to dislike? I'll tell you why, because it's right.
